" Men who regularly eat soy food have lower concentrations of sperm than those who do not, a new study has revealed. A study involving 99 men who had attended a fertility clinic between 2000 and 2006 found that those who ate the most soy food had 41 million sperm per millilitre less than men who did not eat soy products. As the &amp;#039;normal&amp;#039; concentration of sperm ranges from 80-120 million per millilitre, this reduction represents a large proportion of sperm. The findings reflect previous research on animals which found a link between high consumption of soy-derived isoflavone compounds and infertility. Commenting on the findings, which are published in the journal Human Reproduction, Harvard research fellow Dr Jorge Chavarro revealed: &amp;#039;Men in the highest intake group had a mean soy food intake of half a serving per day - in terms of their isoflavone content that is comparable to having one cup of soy milk or one serving of tofu, tempeh or soy burgers every other day.&amp;#039; However, soy isoflavones are thought to help lower a person&amp;#039;s risk for disease, ease menopause symptoms, and protect against osteoporosis. \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
